Metric System The metric system is a measurement system developed by France. The metric system provided the a measurement system that: Universal Measurement System (understood throughout the world) Eliminated Fractions Based on the number 10 (easy conversions)

Metric System (cont.) The metric system is based off of certain base units of different types of measurement. The base units are: grams (mass), liters (volume), meters (distance), seconds (time) The base units represent the center of the metric system. The system also uses prefixes to describe measurements that are smaller or larger compared to the base.

Metric Prefixes and Values in Equalities: Abbreviation M k h da g, L, s, m d c m µ Prefix Mega Kilo Hecto Deca Base Deci Centi Milli Micro Value 106 103 102 101 1 YOU WILL NEED TO MEMORIZE THE NAMES, ABBREVIATIONS, AND ORDER OF THE PREFIXES. **YOU WILL NOT NEED TO MEMORIZE THE VALUES**

Creating Equalities using the Metric System: Rules for building equalities: Always relate the prefixes to the BASE. Identify the larger unit. (prefixes on the left are the largest) Give the larger unit the number 1. Plug the ‘value’ in for the smaller unit. Example: Megagrams (Mg) to grams (g)

Metric Excel Problems: (base prefix) Convert 15 m to km: Convert 500 cg to g: Convert 0.0065 microliters to liters:

Metric Excel Problems: (prefix prefix) Convert 0.098 ms to Ms: Convert 6 dam to µm: Convert 0.0065 dL to hL:
